DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a closed coal powder conveying device includes a base plate 1, two fixed plates 13 are fixedly connected to the top of the base plate 1, an adjustment component is arranged between the two fixed plates 13, a displacement plate 5 is arranged on the top of the adjustment component, a fixed frame 3 is fixedly connected to the top of the displacement plate 5, a conveyor belt 4 is fixedly installed inside the fixed frame 3, a through hole 6 is opened at the bottom of the fixed frame 3, a cleaning component is arranged at the bottom of the fixed frame 3, and a collecting box 2 is fixedly connected to the top of the displacement plate 5.

[0022] First, when the angle of the conveyor belt 4 needs to be adjusted to adapt to different working scenes or other equipment for docking, the adjustment component is started to operate, thereby driving the angle of the fixed frame 3 to be adjusted, and then driving the angle of the conveyor belt 4 to be adjusted. In this way, the conveying angle can be adjusted according to actual needs to adapt to different sites and process requirements, thereby improving the applicability and flexibility of the device. Then, during transportation, the coal powder adheres to the surface of the conveyor belt 4. At this time, the surface of the conveyor belt 4 can be automatically cleaned and collected by starting the cleaning component, thereby avoiding the problem of increasing more manpower and time costs for subsequent cleaning of the conveyor belt 4, thereby increasing the practicality of the device.

[0023] like Figure 1-Figure 4 As shown, the adjustment component includes a reciprocating screw 15, which is rotatably connected between two fixed plates 13, wherein a first motor 12 is fixedly installed on one side of one of the fixed plates 13, and one end of the output shaft of the first motor 12 is fixedly connected to one end of the reciprocating screw 15. The adjustment component also includes a displacement block 14, which is slidably connected to the top of the base plate 1, and a threaded groove is provided inside the displacement block 14 and is threadedly connected to the outer side of the reciprocating screw 15. A second connecting rod 16 is rotatably connected between the outer side of one of the fixed plates 13 and the bottom of the displacement plate 5, and a first connecting rod 11 is rotatably connected between the outer side of the displacement block 14 and the second connecting rod 16. A limiting plate 17 is fixedly connected to the top of the base plate 1, and a limiting groove 19 is provided inside the limiting plate 17. The limiting groove 19 is slidably connected to the limiting rod 18, and both ends of the limiting rod 18 are fixedly connected to the inside of the displacement plate 5.

[0024] When adjusting the angle of the conveyor belt 4, the reciprocating screw 15 is driven to rotate by starting the output shaft of the first motor 12, and the displacement block 14 is driven to slide on the top of the base plate 1, and then the first connecting rod 11 is driven to rotate and the second connecting rod 16 is driven to rotate at the bottom of the fixed plate 13 and the displacement plate 5, so as to lift one side of the displacement plate 5, and then when the displacement plate 5 moves, the limiting rod 18 is driven to slide inside the limiting groove 19, so as to limit the displacement plate 5 and make its movement smoother, and then the displacement plate 5 drives the conveyor belt 4 to tilt synchronously when it is lifted, so as to reduce the resistance and friction of the coal powder inside it during the transportation process, reduce energy consumption, and improve the transportation efficiency.

[0025] like Figure 1-Figure 4 As shown, the cleaning assembly includes two vertical plates 8, which are fixedly connected to the bottom of the fixed frame 3, and a mounting plate 9 is rotatably connected between the two vertical plates 8.

[0027] The utility model provides a closed coal powder conveying device, and the specific working principle is as follows: first, when adjusting the angle of the conveyor belt 4, the reciprocating screw 15 is driven to rotate by starting the output shaft of the first motor 12, and the displacement block 14 is driven to slide on the top of the bottom plate 1, and then the first connecting rod 11 is driven to rotate and the second connecting rod 16 is driven to rotate at the bottom of the fixed plate 13 and the displacement plate 5, so that one side of the displacement plate 5 is lifted, and then when the displacement plate 5 moves, the limiting rod 18 is driven to slide inside the limiting groove 19, so that the displacement plate 5 is limited and the movement is smoother, and then the displacement plate 5 drives the conveyor belt 4 to tilt synchronously when lifting, so that the coal powder inside it reduces resistance and friction during the transportation process, reduces energy consumption, and improves the transportation efficiency. Finally, when cleaning, the output shaft of the drive motor 7 is started to rotate and drive the mounting plate 9 to rotate and drive the bristles on one side of the brush plate 10 to contact the bottom of the conveyor belt 4, so that the coal powder adhering to the conveyor belt 4 is swept into the inside of the collecting box 2.
